Genetic Invasion
What makes it different from all the tower defences you've played so far is that is uses genetic algorithm to make the enemies evolve. No more scripted increasing difficulty system. The enemies adapt themselves. You improve your defence, they are going stronger. You have a minefield to protect you, they begin to fly. You build a whole lot of anti-air turret, they stop flying. You can guess how that ends : you lose. GeneticInvasion is still in alpha stage, so do not expect it to be perfect, bugless or even crashless.
